Is this a pool scam?

 
I'm mining on http://fairquark.dyndns.org:9650


 
For the last Block (19306) Address  qXZhMBQ8nxQ9pdV9iZXxiUtdmvVs9jiPNi gets 555.88566 FRQ.
 
Its on the same block, like my payoutaddress qPjKF7rvpYHV5GJHNzxtFjn4hx3cCTFcRU (15.16519 FRQ).

So this guy has cpu 37 as fast as mine?
 
My Performance on the pool is 25.5kH/s, his should be 925kH/s, or to be said 1 MH/s.
 
But on the pool Stats, there is no such Address? And nobody with this hashingpower?
 
Is this a pool scam?
